Hollow glass balls are hollow spherical powdered inorganic nonmetallic materials with a particle-size of 5-100mm. The wall thickness is 1-2mm. Their compressive strength is 3-125MPa.

The following is a list of the most recent articles about Hollow Glass Beads Sphere Hollow Glass Beads : What is hollow Glass Microsphere? Hollow glass microspheres are also called microballoons. Their diameter can range from 10 micrometers to 300 micrometers. Hollow spheres fill composite materials like lightweight concrete or syntactic bubble foam. The hollow spheres can be used to fill lightweight composite materials like syntactic polymer foam and lightweight concrete. Hollow glass bead This is a special type of glass bead that is less dense and has a lower thermal conductivity. It's a new type of micron grade light material, developed in 1950s and 60s. Its primary component is borosilicate. The particle size is 10250mm with a wall thickness 12mm. Hollow glass beads feature high compressive strengths, high melting points, high resistivity as well as low thermal conductivity.
Hollow glass microspheres Micro balloons (also known as bubbles) are formed from borosilicate and sodium salt glass mixtures. They have low density, and they're resistant to heat and chemicals. The walls are made of Glass microspheres The spheres are typically rigid and about 10% thicker than their diameter. Spherical particles are available in a variety of densities ranging from 0.06g/C3 to 0.80g/C3, and particle sizes from 5um to180um. The compressive strength is determined by the thickness of the wall of the hollowed sphere. This, in turn, is influenced by the density. Hollow glass sphere Chemically stable, nonflammable, and nonporous. Excellent water resistance. It is a trusted worldwide brand.

Hollow Glass Sphere Hollow Glass beads Product Performance:
Hollow glass microspheres consist of hollow glass microspheres at the micron level with a smoothed surface. It is made up of borosilicate, which is the main chemical component. The sphere is hollow and transparent under an electron microscope. Hollow glass beads possess low density, good strength, resistance to acid and alkali, low thermal conductivity and electrical insulation, among other qualities. These new materials are multi-functional and have excellent fluidity, chemical stability.

What are Hollow Glass Beads Sphere Hollow Glass Beads Produced?
How do you make microspheres of glass?
1. Glass powder method
The glass powder method involves passing pre-prepared powdered glass containing SO3 through the flame between temperatures of 1100-1500. Due to the increase in solubility, SO3 as well as other gases in the glass are released from the glass. In addition, due to surface tension, the glass powder becomes round under high temperatures. The spillage gas forms hollow glass beads when it is sealed within the spherical particle.
2. Spray granulation is a method of granulation.
Spray granulation is done in advance using a special auxiliary (boric, urea or ammonium pentaborate). The solution is injected into the spray drying machine, which is then dried to a specific particle size.
3. The droplet method
The liquid drop technique uses the same raw material as the spray-granulation method. The same quantity of ammonium-perborate-aqueous solution (10%, M (SiO2) = M (Na2O), 500 copies each of the raw materials is used. After evenly mixing, the hollow beads are sprayed onto the spray dryer tower.
4. Dry gel method
The alkyl sodium was added to dilute Hydrochloric Acid and decomposes with water. The gel was dried twice at 60°C and 150°C and then crushed in a ballmill. After grading was completed, dried gel powder was obtained. This was then foamed up in an electric vertical furnace at 1280.

Applications Hollow Glass Beads Sphere Hollow Glass Beads :
Hollow glass microspheres have many applications, including glass fiber reinforced products, composite foam, artificial wood, compound, sound insulation, heat preservation, bowling material, low density cement, sealing materials, lightweight, resin, handicrafts such as the wall-hanging frame, sandwich-layer structure of lightweight packaging material, electronic industry and lightweight concrete.
Hollow glass microspheres are also coated to provide a conductive surface. While maintaining the weight reduction associated with hollow and low-density material, conductive coatings with optimized thickness can provide spherical particle with excellent shielding and conducting properties. These conductive microbubbles can be used in military applications, biotechnology and medical devices as well electronics.
Hollow glass beads can reduce weight and improve sound insulation. The products are also resistant to cracking and have good reprocessing properties. It is used in the manufacture of composite materials like wood, engineering plastics, insulation material, rubber, buoyancy materials, FRPs, artificial marbles, man-made stones, the oil and gas industry, aerospace and communications, new high-speed cars and ships, thermal insulation coatings and adhesives.
